Im gonna say "A" was like nepoleon and the amount in the drink made him puke and also makig him live cause the pison was ejected. As for "B" He siped slow so the pioson was able to absorb into the body. In other words A drank so quick his body ejected the toxins before most were absorbed while B drank slow and the toxins were slowly absorbed into the body but all the toxins wer absorbed.
